Update Changelog

  • Property mode set to 100644
File size: 12.9 KB
1** Version 0.10.0 (UNRELEASED)
2- Support for stapling mutiple OCSP responses (TLS 1.3 only)
3- The test infrastructure has been mostly rewritten in Python, note
4  the new dependencies (Python 3, Pyyaml).
5- Server certificates are checked for the must-staple TLS feature
6  extension, stapling must be enabled if so.
7- Compatibility fix for GnuTLS 3.6.11 in the test suite: Handle
8  certificate type in TLS session information strings
10** Version 0.9.1 (2019-11-29)
11- Fix possible segfault (NULL pointer dereference) on failed TLS
12  handshake. Calling ssl_var_lookup() after a failed handshake could
13  lead to GnuTLS session information functions being called on a NULL
14  session pointer, leading to segfault.
15- Remove URLs from expected error responses in the test suite. Apache
16  HTTPD removed request URLs from canned error messages to prevent
17  misleading text/links being displayed via crafted links
18  (CVE-2019-10092). Adjust the expected error responses in our tests
19  so they can pass again.
20- Test suite: Ignore "Content-Length" header of responses. Thanks to
21  Krista Karppinen!
22- Add a section about module dependencies on socache to the handbook
23- Restructure the manpage build and move it to section 5 (config
24  files)
25- Test suite: Restructure certificate directories
27** Version 0.9.0 (2019-01-23)
28- Security fix: Refuse to send or receive any data over a failed TLS
29  connection (commit 72b669eae8c45dda1850e8e5b30a97c918357b51). The
30  previous behavior could lead to requests on reverse proxy TLS
31  connections being sent in plain text, and might have allowed faking
32  requests in plain text.
33- Security fix: Reject HTTP requests if they try to access virtual
34  hosts that do not match their TLS connections (commit
35  de3fad3c12f53cdbf082ad675e4b10f521a02811). Additionally check if SNI
36  and Host header match. Thanks to Krista Karppinen for contributing
37  tests!
38- OCSP stapling is now enabled by default, if possible. OCSP responses
39  are updated regularly and stored in a cache separate from the
40  session cache. The OCSP cache uses mod_socache_shmcb by default
41  (if the module is loaded, no other configuration required).
42- Session tickets are now enabled by default if using GnuTLS 3.6.4 or
43  newer. GnuTLS 3.6.4 introduced automatic rotation for the used key,
44  and TLS 1.3 takes care of other reasons not to use tickets while
45  requiring them for session resumption. Note that there is currently
46  no mechanism to synchronize ticket keys across a cluster of servers.
47- The internal cache implementation has been replaced with
48  mod_socache. Users may need to update their GnuTLSCache settings and
49  load the appropriate socache modules.
50- ALPN (required for HTTP/2) now works correctly with different
51  "Protocols" directives between virtual hosts if building with GnuTLS
52  3.6.3 or newer. Older versions require identical "Protocols"
53  directives for overlapping virtual hosts. Thanks to Vincent Tamet
54  for the bug report!
55- ALPN is now supported for proxy connections, making HTTP/2 proxy
56  connections using mod_proxy_http2 possible.
57- GnuTLSPriorities is optional now and defaults to "NORMAL" if
58  missing. The same applies to GnuTLSProxyPriorities (if TLS proxy is
59  enabled).
60- The manual is now built as a manual page, too, if pandoc is
61  available.
62- OpenPGP support has been removed.
63- Don't require pem2openpgp for tests when building without MSVA
64  support.
66** Version 0.8.4 (2018-04-13)
67- Support Apache HTTPD 2.4.33 API for proxy TLS connections
68- Support TLS for HTTP/2 connections with mod_http2
69- Fix configuration of OCSP stapling callback
71** Version 0.8.3 (2017-10-20)
72- Use GnuTLS' default DH parameters by default
73- Handle long Server Name Indication data and gracefully ignore
74  unknown SNI types
75- Send SNI for proxy connections
76- Deprecate OpenPGP support like GnuTLS did (will be removed
77  completely in a future release)
78- Do not announce session ticket support for proxy connections
79- Minor documentation updates (SSL_CLIENT_I_DN, reference for SNI)
80- Test suite: Simplify handling of proxy backend servers and OCSP
81  responders
82- Test suite: stability/compatibility fixes
84** Version 0.8.2 (2017-01-08)
85- Test suite: Ensure CRLF line ends in HTTP headers
86- Test suite, gen_ocsp_index.c: Handle serial as fixed order byte array
88** Version 0.8.1 (2016-12-20)
89- Bugfix: Use APR_SIZE_T_FMT for portable apr_size_t formatting
91** Version 0.8.0 (2016-12-11)
92- New: Support for OCSP stapling
93- Bugfix: Access to DBM cache is locked using global mutex
94  "gnutls-cache"
95- Bugfix: GnuTLSSessionTickets is now disabled by default as described
96  in the handbook
97- Fixed memory leak while checking proxy backend certificate
98- Fixed memory leaks in post_config
99- Safely delete session ticket key (requires GnuTLS >= 3.4)
100- Improved error handling in post_config hook
101- Various handbook updates
102- Internal API documentation can be generated using Doxygen
103- Unused code has been removed (conditionals for GnuTLS 2.x and Apache
104  versions before 2.2, internal Lua bytecode structure last used in
105  2011).
106- Test suite: Fixed locking for access to the PGP keyring of the test
107  certificate authority
108- mod_gnutls can be built using Clang (unsupported)
110** Version 0.7.5 (2016-05-28)
111- Sunil Mohan Adapa reported retry loops during session shutdown in
112  cleanup_gnutls_session() due to gnutls_bye() incorrectly returning
113  GNUTLS_E_INTERRUPTED or GNUTLS_E_AGAIN. Setting the GnuTLS session
114  errno in mgs_transport_write() fixes the problem.
115- Import Daniel Kahn Gillmor's patches for GnuPG v2 support from the
116  Debian package.
117- Build system improvements that allow VPATH builds and get "make
118  distcheck" to work
120** Version 0.7.4 (2016-04-13)
121- Support SoftHSM 2 for PKCS #11 testing
122- Increase verbosity of test logs
124** Version 0.7.3 (2016-01-12)
125- Update test suite for compatibility with GnuTLS 3.4, which has
126  stricter key usage checks and priorities than 3.3.
127- Write non-HTML output to mod_status reports if AP_STATUS_SHORT is
128  set (mod_status sets it for requests with the "auto" parameter, e.g.
129  https://localhost/server-status?auto).
130- Register "ssl_is_https" function so the special mod_rewrite variable
131  %{HTTPS} works correctly with mod_gnutls. The new test case for this
132  requires Wget or curl. Fixes Debian bug #514005.
133- Test suite servers listen on IPv4 *and* IPv6 loopback addresses by
134  default (other addresses configurable), which should fix failures
135  due to localhost randomly resolving to either on some distributions.
136- Isolate tests using network namespaces, if possible. This avoids
137  port conflicts with other test cases (so they can run in parallel)
138  and host services.
139- Support for local Apache drop-in config files in the test suite
140  (e.g. to load additional modules needed on Fedora).
141- Try to use markdown to build HTML documentation if pandoc is not
142  available.
143- Disable use of flock if it is unavailable or does not support
144  timeouts (the latter caused the build to fail on Debian Hurd).
145- New test: Disable TLS 1.0 (regression test for Debian bug #754960).
147** Version 0.7.2 (2015-11-21)
148- Bugfix: Non-blocking reads in the input filter could lead to a busy
149  wait in the gnutls_io_input_read function, causing high load on
150  Keep-Alive connections waiting for data, until either more data
151  could be received or the connection was closed. The fix is to pass
152  EAGAIN/EINTR results up to the input filter so they can be handled
153  properly.
154- Close TLS session if the input filter receives EOF (mostly relevant
155  for proper termination of proxy connections).
156- Remove dependency on APR Memcache, which is replaced by the newer
157  version included in the APR Utility Library (libaprutil).
158- Remove dependency on bc. It was used for floating point arithmetic
159  in the test suite, the calculations have been changed to use
160  integers and pure bash code.
162** Version 0.7.1 (2015-10-18)
163- Improved handling of PKCS #11 modules: mod_gnutls now loads either
164  modules specified using GnuTLSP11Module, or the system defaults, but
165  not both. Thanks to Nikos Mavrogiannopoulos for the report and
166  initial patch!
167- Initialize variables to safe defaults during client certificate
168  verification. Certain error code paths did not set them, but they
169  should never be hit due to config validation. This adds another line
170  of defense.
171- Enable C99 support via autoconf
172- Test suite improvements. Most importantly, automake now handles
173  environment setup without any external make calls. Rules to build
174  the certificates are included from the old test makefile. Note that
175  the dependency on GNU make is not new (the test makefile always used
176  GNU make syntax), it just wasn't listed explicitly.
178** Version 0.7 (2015-07-12)
179- Security fix for TLS client authentication (CVE-2015-2091)
180- Bug fixes that enable support for reverse proxy operation
181- Various test suite improvements. Tests are configured through autoconf,
182  so the test suite now works for builds without Monkeysphere support.
183- Add support for TLS connections to back end servers when operating as a
184  reverse proxy (X.509 authentication only at the moment).
185- PKCS #11 support for server keys and certificates
186- Use strict compiler arguments by default (-Wall -Werror -Wextra)
187- Allow limiting the size of certificates exported as SSL_SERVER_CERT
188  and SSL_CLIENT_CERT through the GnuTLSExportCertificates directive
190** Version 0.6 (2014-02-17)
191- Generating DH Params instead of using static ones.
192- Now considering ServerAlias Directives.
193- Major Legacy Code Cleanup.
194- html and pdf and manual documentation generated from markdown sources
195- support monkeysphere validation agent (MSVA) client-certificate verification
196- wider test suite
197- GnuTLSExportCertificates off by default
199** Version 0.5.10 (2011-07-12)
200- Patched a bug responsible for excessive memory consumption by mod_gnutls.
201- Support for proxying from SSL to plain HTTP was added (ie. proxy termination).
203** Version 0.5.9 (2010-09-24)
204- GnuTLSCache none is now an allowed option.
205- Corrected behavior in Keep-Alive connections (do not
206  terminate the connection prematurely)
207- The GnuTLSCache variable now can be given the specific
208  option "gdbm" instead of "dbm". "dbm" will use the berkeley
209  db type of libapr while gdbm will force gdbm to be used.
210  sdbm is no longer being used due to serious limitations.
212** Version 0.5.8 (2010-08-18)
213- Session tickets are enabled by default.
214- Fixes some segmentation faults noticed in some
215  configurations.
217** Version 0.5.7 (2010-07-01)
218- Force usage of SDBM. For some reason the default in
219  my system had issues after reaching a limit of entries.
220  SDBM seems stable so force it.
221- Optimizations in session caching.
222- Added support for session tickets. This allows a
223  server to avoid using a session cache and still support
224  session resumption. This is at the cost of transporting
225  session data during handshake. New option
226  GnuTLSSessionTickets [on|off]
227- Depend on gnutls 2.10.0 to force support for safe
228  renegotiation.
230** Version 0.5.6 (2010-03-24)
231- Corrected issue with firefox and long POST data (by
232  handling EINTR and EAGAIN errors in read).
233- Added support for chained client certificates
234- Corrected more issues related to double frees
237** Version 0.5.5 (2009-06-13)
238- Removed limits on CA certificate loading. Reported by
239  Sander Marechal and Jack Bates.
240- Do not allow sending empty TLS packets even when instructed to.
241  This had the side effect of clients closing connection.
243** Version 0.5.4 (2009-01-04)
244- mod_gnutls.h: modified definition to extern to avoid compilation
245  errors in darwin.
246- Added patch to fix issue with mod_proxy. Investigation and patch by Alain
247  Knaff.
248- libgnutls detection uses pkg-config.
250** Version 0.5.3 (2008-10-16)
251- Corrected bug to allow having an OpenPGP-only web site.
252- Increased Max handshake tries due to interrupted system calls.
254** Version 0.5.2 (2008-06-29)
255- Depend on gnutls 2.4 which has openpgp support in main library.
257** Version 0.5.1 (2008-03-05)
258- Added --disable-srp configure option
259- Better check for memcache (patch by Guillaume Rousse)
260- Corrected possible memory leak in DBM support for resuming sessions.
262** Version 0.5.0-alpha (2008-01-24)
263- Added support for OpenPGP keys. The new directives are:
264  GnuTLSPGPKeyringFile, GnuTLSPGPCertificateFile, GnuTLSPGPKeyFile
266** Version 0.4.2 (2007-12-10)
267- Added support for sending a certificate chain.
268- Corrected bug which did not allow the TLS session cache to be used.
269- Do not allow resuming sessions on different servers.
271** Version 0.4.1 (2007-12-03)
272- Added support for subject alternative names in certificates.
273Only one per certificate is supported.
274- New enviroment variables: SSL_CLIENT_M_VERSION, SSL_CLIENT_S_SAN%,
276- The compatibility mode can now be enabled explicitely with the
277%COMPAT keyword at the GnuTLSPriorities string. It is no longer the default.
278- Check for GnuTLSPriorities directive. This corrects a segfault. Thanks
279to David Hrbáč.
280- Better handling of GnuTLSDHFile and GnuTLSRSAFile.
281- No longer default paths for RSA and DH parameter files.
